[TUTORIAL] Upgrading mysql 5.1 to 5.4 + phpmyadmin CENTOS 6.4

[Me.B]

TokuDB does not support foreign keys and is not compatible 100% with innoDB. So it's quitly different here as a choice.

Would be an issue for a lot of CMS. Also tokuDB require at least 50% of ram for cache ( in GB if available).

Require mySQL 5.5 ( not available in centos 6.x branch!)

Also for MySQL updrade beware using REMI repos will cause a lot of dependencies conflict that would be hard to resolve!
